1. What is Boyle's Law?

Boyle's Law states that the pressure of a given mass of an ideal gas is inversely proportional to its volume at a constant temperature. This fundamental gas law describes the relationship between pressure and volume in a closed system.

2. How Does the Calculator Work?

The calculator uses Boyle's Law equation:

Where:

• \( P1 \) — Initial pressure (Pa)
• \( V1 \) — Initial volume (m³)
• \( V2 \) — Final volume (m³)
• \( P2 \) — Final pressure (Pa)

Explanation: The equation shows that as volume increases, pressure decreases proportionally, and vice versa, when temperature remains constant.

3. Importance of Boyle's Law

Details: Boyle's Law is crucial for understanding gas behavior in various applications including respiratory physiology, scuba diving, syringes, and many industrial processes involving gases.

4. Using the Calculator

Tips: Enter initial pressure in Pascals (Pa), initial volume in cubic meters (m³), and final volume in cubic meters (m³). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are the assumptions of Boyle's Law?
A: Boyle's Law assumes constant temperature, ideal gas behavior, and a closed system with no gas molecules entering or leaving.

Q2: What units should I use for the calculation?
A: While Pascals and cubic meters are used here, any consistent pressure and volume units can be used as long as they're the same for both initial and final states.

Q3: Does Boyle's Law apply to real gases?
A: Boyle's Law applies exactly to ideal gases and approximately to real gases at moderate temperatures and pressures away from condensation points.

Q4: What happens if temperature changes?
A: If temperature changes, the combined gas law (incorporating Charles's Law) must be used instead of Boyle's Law alone.

Q5: Can I use this for liquids?
A: No, Boyle's Law specifically applies to gases. Liquids are generally considered incompressible and don't follow this relationship.
